C-states affect on overclocking?

post #1 of 4
Thread Starter 
How much do c3 and c6 states affect 3770k overclocks? im stable at 1.3v with c3/c6 on and stable at 1.25v with them off...


why does turning them off make it that much more stable


my offset is -0.035 lol

Because the power states C3 reduce the clock signals and C6 reduces the voltage in the CPU. Meaning having C3/C6 power states on you have to push slightly more voltage to get your clocks stable.

These CPUs can allow individual cores to go into various C States as well as the entire CPU package. When overclocking my 3570K to 4.5 GHz, I find that letting the individual cores go into C3/C6 does not cause any problems but the CPU package C States can cause some random, usually light load, blue screens so I turn them off. Run RealTemp if you want to see what C States are enabled on your computer.
